Similar story. Doctors told my mother: "Bad news; good news." The bad news was she had Leukemia; the good news was she had the type where she could have a fairly long life expecentancy. The result was she lived an almost normal life for just short of 20 more years.
She had a great doctor at MD Anderson: Dr Michael Keating and they became close friends. She was fortunate to have great support from family and friends. She had a positive attitude; time and time again, she would say: "I do not have time to be sick, I have too much to do." She kept active until the very end.
Yes, there were times when she had difficult periods. In her case, she always bounced back. She kept looking forward and making future plans. After she died, the doctor told us that the number one thing that kept her alive was her attitude and positive determination to go forward.
I wish you well. There will be hard times. One of the best things you can do is to keep a positive environment around you and keep a positive attitude. Stay well and keep living life to the best of your ability.
